The most common cause of gum pain is periodontitis, which causes inflammation, redness and swelling of the gums, and redness and swelling naturally leads to pain. There are also some accompanying symptoms of periodontitis, such as periodontal abscesses, which are very tense and have high pressure in the periodontal abscess tissue and can also cause painful discomfort, both of which are very common in periodontology. Some other causes of gum pain are necrotizing gingivitis or periodontitis, and there are some patients with low resistance, malnutrition or AIDS patients, which can lead to very pronounced gum pain. Also, inflammation of the wisdom teeth is very common and can also lead to gum pain. There are also some relatively rare or rare in periodontology that may be encountered in other departments, such as mucosal diseases, such as oral herpes virus infections that spread to the gums, or other mucosal diseases that spread to the gums can also lead to gum pain and require prompt consultation. Regardless of the cause of gum pain, the cause needs to be identified, diagnosed and treated accordingly.
